Dear SJ,
Losing a best friend is never easy.
Your problem, is not just that you miss your best friend, it is that you feel empty and lost without her friendship.
It takes time to get over a lost, and during that time, your mind is getting used to a new way of being. This is usually a good thing, even if it feels like a bad thing.
Now that you are on your own, you are being forced to learn to be by yourself and to rely upon your own inner voice for guidance. I am sure that this feels strange for you, but if you can hang on for a bit longer, it may work to your advantage.
Best friends are cool, but it is important to know the difference between missing someone and being too independent upon them.
At your age, girls do tend to stick together and having a good boyfriend may not yet be the better choice. Your friend is leaving you, her best friend, for a boyfriend. Boyfriends are completely different from best friends. The distinction is that boyfriends come and go, while girl friends often stay in your life throughout high school, and even afterwards. It is a completely different sort of bond.
I suggest that you take advantage of this period in your life to expand your horizons. Enjoy the freedom of having no best friend for a while, and hang with the group. By the time your former best friend breaks up with her boyfriend, you will be in a completely different place, a far better place.
And, by the way, next time you feel empty and lost, try to write about it in a diary. In several months, you will look back and read it with curiosity about yourself. “Who was I then, and what could I have been thinking?”Judging from the letter, SJ’s problem was that she didn’t know _______ .
| A．whether to give up her best friend |
| B．what to do without her best friend |
| C．whom to choose between two friends |
| D．how to stop missing her former friend |
The underlined part “a new way of being” (in Paragraph 3) refers to the situation in which SJ has to _______.
| A．find a new friendship | B．live without her boyfriend |
| C．learn to give up | D．learn to be independent |
The writer believes by the time SJ’s former friend loses her boyfriend, SJ will _______.
| A．take revenge on her former friend |
| B．comfort her former friend |
| C．feel more independent and confident |
| D．continue friendship with her former friend |
What does the last paragraph seem to suggest?
| A．Unhappy experiences are easy to forget. |
| B．Keeping a diary helps correct oneself. |
| C．SJ will get over her problem soon. |
| D．One shouldn’t forget the past experiences. |
Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need.
We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place. The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place.
Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us.
We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.The author uses figures in Paragraph 2 to show _______.
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the rapid growth of super markets |
| D．the fact of packaging overuse |
According to the text, recycling ______.
| A．helps control the greenhouse effect |
| B．means burning packaging for energy |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
What can be inferred from Paragraph 4?
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．It is improper to judge quality by packaging. |
| D．Other products are better packaged than food. |
What can we learn from the last paragraph?
| A．Fighting wastefulness is difficult. |
| B．Needless material is mostly recycled. |
| C．People like collecting recyclable waste. |
| D．The author is proud of their consumer culture. |
We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.What has the new study of more than 260,000 people found?
| A．Sugary sodas aren’t good for the physical health of old people. |
| B．Americans have a special tooth for sweet foods. |
| C．Sweetened soft-drinks may increase the risk of depression. |
| D．Sweetened soft-drinks have important physical consequences. |
What do we know about the process of the study?
| A．About twenty-six thousand people participated in it. |
| B．The oldest participants were below 80 when the study was over. |
| C．Most of the participants had depression when the study was over. |
| D．The study lasted more than ten years from the beginning to the end. |
It is implied in the passage that ______.
| A．more research is needed to confirm the new findings |
| B．the new findings aren’t consistent with any previous findings |
| C．cutting one’s sodas intake will surely reduce one’s depression |
| D．the new findings won’t have an impact on people’s drinking habits |
What should you drink in order to reduce the risk of depression?
| A．Sodas. | B．Unsweetened coffee. |
| C．Sugary coffee. | D．Fruit punch. |
Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her three-year-old son, Michael, prepare for a new sibling. They find out that the new baby is going to be a girl, and day after day, night after night, Michael sings to his sister in Mommy's tummy.
The pregnancy progresses normally for Karen. But complications arise during delivery. Finally, Michael's little sister is born. But she is in serious condition. With siren howling in the night, the ambulance rushes the infant to the intensive care unit at St. Mary's Hospital.
The little girl gets worse. The doctor tells the parents, "There is very little hope. Be prepared for the worst." Karen and her husband have fixed up a special room in their home for the new baby — now they plan a funeral.
Michael, keeps begging his parents to let him see his sister, "I want to sing to her," he says. But kids are never allowed in Intensive Care. However, Karen makes up her mind. She will take Michael whether they like it or not.“If he doesn't see his sister now, he may never see her alive.” She dresses him in an oversized scrub suit and marches him into ICU. The head nurse recognizes him as a child and bellows, "Get that kid out of here now! " The mother, the usually mild-mannered lady glares steel-eyed into the head nurse's face, her lips a firm line. "He is not leaving until he sings to his sister!" Karen tows Michael to his sister's bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing.
"You are my sunshine, my only sunshine, you make me happy when skies are gray”
Instantly the baby girl responds. The pulse rate becomes calm and steady.
"You never know, dear, how much I love you. Please don't take my sunshine away "
The ragged, strained breathing becomes as smooth as a kitten's purr.
Keep on singing, Michael. Tears conquer the face of the bossy head nurse as well as Karen.
Funeral plans are scrapped. The next, day — the very next day — the little girl is well enough to go home!

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的)tests，for everything from baldness to breast cancer，and the list is growing．Question is do you really want to know what might eventually kill you? For instance，Nobel Prize-winning scientist James Watson，one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your 1ife as you wait for that disease to hit you．It could really mess you up．”Said Dr．Robert Green，a Harvard geneticist.
“Every ache and pain，”Smith suggested，could be understood as“the beginning of the e nd．”“That’s right．If you ever worried you were at risk for Alzheimer's disease，then every time you can’t find your car in the parking lot，you think the disease has started．”
Dr．Green has been thinking about this issue for years．He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s．It was thought that people who got bad news would，for lack of a better medical term，freak out．But Green and his team found that there was “no significant difference”between how people handled good news and possibly the worst news of their lives．In fact，most people think they can handle it．People who ask for the information usually can handle the information，good or bad，said Green．The first paragraph is meant to _________________．
| A．ask some questions | B．introduce the topic |
| C．satisfy readers，curiosity | D．describe an academic fact |
Which of the following is true of James Watson?
| A．He is strongly in favor of the present genetic tests. |
| B．He is more likely to suffer from Alzheimer's disease． |
| C．He believes genetic mapping can help cure any disease. |
| D．He doesn’t want to know his chance of getting a disease． |
According to Paragraphs 3 and 4，if a person is at a higher genetic risk，it is ____________.
| A．advisable not to let him know |
| B．impossible to hide his disease |
| C．better to inform him immediately |
| D．necessary to remove his anxiety |
The underlined part“freak out”in Paragraph 5 is closest in meaning to _____________.
| A．break down | B．drop out |
| C．leave off | D．turn away |
The study led by Dr．Green indicates that people ________________.
| A．prefer to hear good news |
| B．tend to find out the truth |
| C．can accept some bad news |
| D．have the right to be informed |
Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects．The software could eventually allow smart phone-armed soldiers to target the location of their enemies．On the home front，the software could be used by everyone，including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it．
“The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，”said Qia Wang，a doctoral student who led the development of the software．“For example，on the battlefield，a soldier needs a rangefinder，compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from War，she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video．”
Wang and his colleagues developed their software to locate and track：
Targets of known size—when the size of the target is known．a single image is enough to pinpoint the target’s location．
Targets of unknown size—If the exact size of a target is unknown，the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target，the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently，our software is limited by the physical abilities of smartphone hardware，but the devices are improving rapidly，”Wang said．“We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．”．From Paragraph 1 we can know that the new software can_______.
| A．determine the speed of moving objects |
| B．1ocate objects in the distance exactly |
| C．defend soldiers against their enemies |
| D．help biologists protect rare animal |
．The example given by Qia Wang is meant to ________________.
| A．make an advertisement |
| B．describe the software briefly |
| C．show the benefits of the software |
| D．present the functions of smartphones |
．How does the software calculate the speed of a moving object?
| A．By taking a short video． | B．By locating its position. |
| C．By taking a single image． | D．By measuring real-life size. |
．What’s Qia Wang’s attitude towards the future of the software?
| A．Casual． | B．Optimistic． |
| C．Cautious． | D．Flexible |
．What is the best title of the text?
| A．Qia Wang，a Talented Doctoral Student |
| B．Use Smartphones to Their Full Potential |
| C．Targeting and Tracking With Smartphones |
| D．Smartphone-armed Soldiers on the Battlefield |
